No regrets. I posted a lot of ideas these last 10 years and many of them were included in the game, I couldn't expect better than that. I never reached that level with The Sims 2/3 & TS2 BBS/TS3 Forums. It was nice to speculate about the future and post polls. Probably the only time of my life that I post over 15k comments.
Check your settings, by default the option is "When I'm following a Forum Discussion, notify me about" : New topics only The other option is "New topics and replies"
I don't have the feeling that Maxis will read the comments (Ideas Corner is gone). At the same time so many ideas have been posted these last 10 years, maybe it's time to wait for the result.
SimGuruRomeo leaves EA, he worked on Project Rene. Maybe it's not cancelled but there is no news. I don't think EA will tell something about it on July 30th (Q1 financial results)
